1. A pet feeder comprising:
a housing;
a heat conduction member, a temperature adjustment structure and a heat dissipation member that are arranged in the housing, the temperature adjustment structure comprising a thermoelectric cooling member and a control module, the thermoelectric cooling member comprising a first side connected to the heat conduction member and a second side that is opposite the first side and in contact with the heat dissipation member, and the control module configured to control the first side of the thermoelectric cooling member to heat or cool;
a tray arranged in the housing and connected to the heat conduction member, the tray defining at least two compartments for placing pet food;
a cover arranged on the tray and defining a window in communication with the at least two compartments; and
an actuating mechanism arranged in the housing and configured to rotate the tray or the cover;
a support member arranged in the housing, and the heat dissipation member, the thermoelectric cooling member and the heat conduction member connected to the support member;
a second heat insulating member arranged between the heat conduction member and the heat dissipation member, and arranged around the thermoelectric cooling member;
a heat conduction block disposed between the thermoelectric cooling member and the heat conduction member; and
a third heat insulating member arranged around the heat conduction block and located between the thermoelectric cooling member and the heat conduction member;
wherein the support member comprises:
a base plate arranged between the second heat insulating member and the third heat insulating member, and defining a through hole for the thermoelectric cooling member to pass through so as to come into contact with the heat conduction block;
at least two first side plates arranged at a side of the base plate facing the heat dissipation member, and defining a second accommodation chamber to accommodate the heat dissipation member and the second heat insulating member; and
at least two second side plates arranged at a side of the base plate facing the heat conduction member, and defining a third accommodation chamber to accommodate the heat conduction block, the third heat insulating member arranged around the at least two second side plates.
